BTW, after thinking on/off awhile. I have (experience with) the
perfect "worst thermal paste".
A. It performs worse than most
generic silicone-based pastes
B. It's been around for decades.
C. It's still manufactured and sold, today.
D. It's still 'useful', despite performing worse than even silicone-based thermal pads.

Basically, it's Diaper Rash Cream but, made w/ a Synthetic Petrol base and
(purposefully) containing nano zinc oxides and alumina
(IIRC, lab testing determined it's mostly zinc oxide)
It's useful for MOSFET TIM, and I've seen ASC (or similar*) used in finished-built products. It stays put, never 'dries out', and can be used well above 100c.

*ASC has a very unique non-Newtonian 'flow' and cleanup. Which, I've seen on/in non-PC related products, typ. on power ICs / FETs
